.TH std::to_string 3 "2024.06.10" "http://cppreference.com" "C++ Standard Libary"
.SH NAME
std::to_string \- std::to_string

.SH Synopsis
   Defined in header <stacktrace>
   std::string to_string( const std::stacktrace_entry& f );  (since C++23)

   Returns a string with a description of f.

   The standard recommends that the description should provide information about the
   contained evaluation, including information from f.source_file() and
   f.source_line().

.SH Parameters

   f - a stacktrace_entry whose description is to be returned

.SH Return value

   A string with a description of f.

.SH Exceptions

   May throw implementation-defined exceptions.

.SH Notes

   Custom allocators support for this function is not provided, because the
   implementations usually require platform specific allocations, system calls and a
   lot of CPU intensive work, while a custom allocator does not provide benefits for
   this function as the platform specific operations take an order of magnitude more
   time than the allocation.

.SH Example


// Run this code

 #include <stacktrace>
 #include <string>
 #include <iostream>

 int main()
 {
     auto st = std::stacktrace::current();
     std::cout <<
         "Description of an empty stacktrace entry:\\n" +
         std::to_string(std::stacktrace_entry{}) << '\\n';
     if (st.size() > 0) {
         std::cout <<
             "Description of a non-empty stacktrace entry:\\n" +
             std::to_string(st[0]) << '\\n';
     }
 }

.SH Possible output:

 Description of an empty stacktrace entry:

 Description of a non-empty stacktrace entry:
 0x0000000000402DE9 in ./prog.exe
